Karel the Robot.

So, I decided to learn some java before I go to college.

I'm still a newbie at this, but do I just suck or is it normal to take hours on just one program? It forces me to think, which is good, but I feel like I'm going so slow.

I've been doing:
http://see.stanford.edu/materials/icspmc...-karel.pdf

Number 1 was super easy, number 2 took me a while to figure out how to get it for all the worlds, and I started number 3.

Anyone want to check my work?
